Question

for a fastener with a class of 8.8, second number denotes the ____________ as a percentage of tensile strength. shear strength proof load yield point clamp load

Explanation:

In fastener class markings like 8.8, the second number represents the yield - point as a percentage of the tensile strength. For example, in 8.8, the first 8 indicates the tensile strength in MPa divided by 100, and the second 8 indicates that the yield point is 80% of the tensile strength.

Answer:

C. yield point
